Inertial Sensor-Based Gait and Attractor Analysis as Clinical Measurement Tool: Functionality and Sensitivity in Healthy Subjects and Patients With Symptomatic Lumbar Spinal Stenosis

open access: yesFrontiers in Physiology, 2018
Objective: To determine if the attractor for acceleration gait data is similar among healthy persons defining a reference attractor; if exercise-induced changes in the attractor in patients with symptomatic lumbar spinal stenosis (sLSS) are greater than ...

DIAGNOSING THE TYPE OF DYNAMICS OF SOCIO-ECONOMIC SYSTEMS USING TOPOLOGICAL TESTS (THE EU IS TAKEN AS AN EXAMPLE) [PDF]

open access: yesВісник Київського національного університету імені Тараса Шевченка. Серія Економіка, 2013
The possibility of practical realization of the simplest elements of topological tests that are used to identify the type of systems’ dynamics is considered in the article. The tests were fulfilled by the means of standard instruments of Microsoft Excel.

The Kuramoto–Sivashinsky equation. A Local Attractor Filled with Unstable Periodic Solutions

open access: yesМоделирование и анализ информационных систем, 2018
A periodic boundary value problem is considered for one version of the KuramotoSivashinsky equation, which is widely known in mathematical physics. Local bifurcations in a neighborhood of the spatially homogeneous equilibrium points in the case when they

Excitatory/inhibitory balance emerges as a key factor for RBN performance, overriding attractor dynamics

open access: yesFrontiers in Computational Neuroscience, 2023
Reservoir computing provides a time and cost-efficient alternative to traditional learning methods. Critical regimes, known as the “edge of chaos,” have been found to optimize computational performance in binary neural networks. However, little attention

Diffusion Chaos in Reaction – Diffusion Boundary Problem in the Dumbbell Domain

open access: yesМоделирование и анализ информационных систем, 2013
We consider a boundary problem of reaction-diffusion type in the domain consisting of two rectangular areas connected by a bridge. The bridge width is a bifurcation parameter of the problem and is changed in such way that the measure of the domain is ...

On a High-Precision Method for Studying Attractors of Dynamical Systems and Systems of Explosive Type

open access: yesMathematics, 2022
The author of this article considers a numerical method that uses high-precision calculations to construct approximations to attractors of dynamical systems of chaotic type with a quadratic right-hand side, as well as to find the vertical asymptotes of ...

Exact Hydrodynamic Attractor of an Ultrarelativistic Gas of Hard Spheres. [PDF]

open access: yesPhysical Review Letters, 2019
We derive the general analytical solution of the viscous hydrodynamic equations for an ultrarelativistic gas of hard spheres undergoing Bjorken expansion, taking into account effects from particle number conservation, and use it to analytically determine
